The switch offers very little or practically no attenuation of the high-speed signals at the outputs, thus preserving the signal integrity to pass stringent requirements. Moreover the device reduces the overall BOM costs by eliminating the need for more costly multi input-output controllers.

Its low ON-resistance and low I/O capacitance result in a very small propagation delay. The combination of SEL1 and SEL2 is used to either disable or enable the desired video channel. Refer to the truth table for the selection of the appropriate channels.
